The new Kinvara 6 is just a few engines short of a turbojet, but you might be fooled when you lace up a pair. Our best-ever PRO-LOCK lacing system delivers the optimal midfoot fit, and teams up with a new breathable mesh to deliver a cool breeze while you're blazing the course. The upper's FLEXFILM overlays have been adjusted to help the shoe move better with your foot, and sit atop the same POWERGRID-enhanced midsole as the previous edition, because, well… It's just that good.
